The Art and Industry of Sandcastles

"You will have to learn something about baileys, parapets, crenelations and keeps -you will have to build as men built for the kings of the green kingdoms of chivalry."
"Walls are the curtain of safety around your stronghold."
"Restormel Castle began as earthworks around a wooden stockage and evolved over hundreds of years to the round shell keep where Edward the Black Prince held court in 1360. Sand castles evolve, too, over a shorter period so that you can hold court before the tide comes in. Build far enough from the incoming tide to finish, but near enough to allow the waves to claim their rightful property. To give the sea its due is part of the rules."
"Pembroke Castle evolved, as your castle might. At first it was a simple tower keep, and it grew as the Earls of Pembroke and the families of the village had time to work at it, and as times made it necessary to have a greater, stronger refuge."
You will treasure it.
